Stainless Steel O-Rings

How To Select Metal Seals

Grothenrath Rubber identifies ring sizes, first by Outside Diameter, then by tube size (cross section) and wall thickness, Materials Used and by letters (where applicable) indication plating, coating, venting and/ or pressure filling.

Example:
Tubular rings

  • 1 3000-125x010-321TCV
  • 2 750-062x012-600AgPF

The first number indications Outside Diameter, with decimal omitted, which would be to three decimal places. Example #1 = 3.00" diameter. #2 = .750" etc. Diameters are always given before plating and are held to +.005"/ .000" tolerance.

The second set of numbers indicate Tube Dimeter and Wall Thickness as in example #1 = 125x010 or .125" tube O.D. by .010" wall. Decimals are alos omitted. Tolerances +/- .001" on the diameters and +/- 10% on wall thicknesses.
